The big difference is that the map in Minecraft is constantly changing which can in turn change players position and potential actions - Quake 3 was comparitively much simpler, more or less just a coordinate and velocity vector.

But I agree, there is no reason for Minecraft performance to be so bad when there are only 2 people on a server just mining one brick at a time!

Not quite. The map in Minecraft changes. But if you optimize the game for the "constantly changing" case, when it usually changes less than 1 block per user per 10 seconds (and even that is high), then you're going to end up with code that doesn't handle normal behavior very well.
